Five and Two
To express the number 25 using only one 5 and one 2, you could write -> 5^2 (this site wouldn't allow posting of a superscript ... however, if you were writing you could express 25 with only a 5 and a 2).
Can you find another way to express 25 using only one 5 and one 2 and two arithmetic operators?

So 5/.2 isn't allowed! Tricky.
sorry Chris ...you're right
To quote Cam, "I feared as much." ;)
LOL. Did you change the question Zaux?
could it be:
-5^2 ...?
No, because that is -25. But it could be (-5)^2. Parenthesis only modify the precedence of operators, they are not operators themselves. So I think you've satisfied the (new!) rules.
yay!
didn't change the problem ... might be time for a visit to your special doctor.... heh heh.
